1. find the volume of a cube with a side length of 4.5 feet.
my answer is- 91.13

2. find the volume of the cube
one side is 3 1/8 inch
my answer- none

3.if the area of the face of a cube is 16 square meters, find the cube’s volume.
my answer-
lengthxwidthxheight which should be 4 m long, 4 m wide, 4 m high
so 4x4x4=64 m³ volume

4.find the length of the side of a cube with a volume of 125 cubic inches.
my answer-
5x5x5=125 cubic inches
side length is 5 inches

5.if a cube is made of 8 unit cubes, what is the cube’s volume in cubic feet?
my answer-
8x8x8= 512
8ft³ = 512 cubic feet

6. kero has a plastic container in the shape of a cube. the length of a side is 20 cm. she wants to fill it with 3 liters of water. can her container hold this amount of water? explain you answer. (1 liter = 1000cm3).
my answer-
20x20x20=8,000 cm³
8,000 cm^3=8 liters
3x1000= 3,000 cm³
3,000cm^3=3 liters
so the container can hold 8 liters so it wouldn't be a problem to hold 3 liters.

7.janet has a cube with a volume of 294 cubic inches. pat has a cube with a surface area of 216 square inches. who has the bigger cube? explain your answer.
my answer-
janet's cube- 6.65³ =294 cubic inches
side length is 6.65
pat's cube- 216÷6=36 square inches
one side face is 6 inches
janet's cube is slightly larger than pat's cube.

8. what is the difference between the surface area of a cube and the volume of a cube? explain your answer by comparing the formulas for each measurement.
my answer-
surface area is measured in square inches or square feet. surface area is a flat area. surface area is 2 dimensional; lengthxwidth

volume is measured in cubic inches or feet (inchesxinchesxinches). volume is the inside of an area. volume is 3 dimensional; lengthxwidthxheight
